A New Conformal Map for Polynomial Chaos Applied to Direction-of-Arrival Estimation via UCA Root-MUSIC [PDF]

Sensors, 2022
The effects of random array deformations on Direction-of-Arrival (DOA) estimation with root-Multiple Signal Classification for uniform circular arrays (UCA root-MUSIC) are characterized by a conformally mapped generalized Polynomial Chaos (gPC) algorithm.

Harmonicity of horizontally conformal maps and spectrum of the Laplacian [PDF]

International Journal of Mathematics and Mathematical Sciences, 2002
We discuss the harmonicity of horizontally conformal maps and their relations with the spectrum of the Laplacian. We prove that if Φ:M→N is a horizontally conformal map such that the tension field is divergence free, then Φ is harmonic. Furthermore, if N

The hypersurfaces with conformal normal Gauss map in Hn+1 and S1n+1 [PDF]

Anais da Academia Brasileira de Ciências, 2008
In this paper, we introduce the fourth fundamental forms for hypersurfaces in Hn+1 and space-like hypersurfaces in S1n+1, and discuss the conformality of the normal Gauss map of the hypersurfaces in Hn+1 and S1n+1.

Genus-zero Whitham hierarchies in conformal-map dynamics [PDF]

, 2006
A scheme for solving quasiclassical string equations is developped to prove that genus-zero Whitham hierarchies describe the deformations of planar domains determined by rational conformal maps.

Approximately Conformal, Equivalent and Equidistant Map Projections [PDF]

Journal of Geodesy and Geoinformation Science, 2022
If geodetic coordinates from an ellipsoid are included in the equations of a projection for mapping a sphere instead of geographical coordinates, the result will be a projection of the ellipsoid into a plane.

Dessins d’enfants, Seiberg-Witten curves and conformal blocks

Journal of High Energy Physics, 2021
We show how to map Grothendieck’s dessins d’enfants to algebraic curves as Seiberg-Witten curves, then use the mirror map and the AGT map to obtain the corresponding 4d N $$ \mathcal{N} $$ = 2 supersymmetric instanton partition functions and 2d Virasoro ...

A new approach to calculating fiber fields in 2D vessel cross sections using conformal maps

Mathematical Biosciences and Engineering, 2023
An arterial vessel has three layers, namely, the intima, the media and the adventitia. Each of these layers is modeled to have two families of strain-stiffening collagen fibers that are transversely helical. In an unloaded configuration, these fibers are

Numerical conformal mapping [PDF]

Mathematics of Computation, 1979
A numerical procedure to determine the discrete conformal mapping of an arbitrary simply connected region onto the open unit disk is described. The method is fast and directly provides an estimate of the global error due to the discretization of the mapping.
